Manley Titanium Exhaust Valve Kit - Small Block GM, Ford, Chrysler

If you're rebuilding the top end of a small block GM, Ford, or Chrysler engine and pushing the limits with high-RPM operation, these Manley Titanium Exhaust Valves are a serious consideration. They're designed to significantly cut down on valve train weight, which is crucial for letting your engine rev higher and more freely. This reduction in mass helps improve overall engine efficiency and allows for compatibility with more aggressive camshaft profiles that demand quicker valve response.

What sets these valves apart is their one-piece forged construction. Unlike some other designs that might use welding, Manley's forging process with controlled grain flow creates a more durable component with fewer potential weak points. They're then meticulously machined on advanced CNC equipment to exacting tolerances, ensuring they seal properly and perform reliably. Manley selects specific titanium alloys that offer a great balance of hardness, ductility, and fatigue strength, especially important for the high temperatures exhaust valves endure. Each valve is put through a strict final inspection to guarantee it meets high precision standards before it ever leaves the factory.

This kit includes 8 exhaust valves, each weighing in at a mere 73 grams. They feature a 1.600-inch head diameter, a 0.3415-inch stem diameter, and an overall length of 5.060 inches. While these are designed for performance, remember that titanium can be more sensitive to impact than steel, so careful installation is key. Always refer to the manufacturer's installation instructions for proper handling and seating.
